The depiction of ideas and thoughts through symbols and pictures led the way to words and finally the origin of writing. Greeks experimented with metals sharp edges, bones and ivory using them as stylus and scribbled marks upon wax tablets. The tablets made in hinged pairs, closed to protect the scribe's notes. Pure hand written text messages originated in Greece, scholar Cadmus invented the written letter, text messages written and send from one individual to the other.
Chiseled pictograph communication earlier by humans transformed into scribbled text by the stylus and wax tablets of the great Greeks was just the foundation of the graphic art form. The Indian ink invented by the Chinese, was a mixture of soot from pine smoke and lamp oil, musk and gelatin. Other cultures developed the basic writing material "ink" from berries, plants, and minerals. In earliest forms of writing use of different colored inks stood for various religious meanings. The early civilizations of Egypt, Rome, and Greeks communication scripts inked on papyrus and parchment papers served the basic paper.
The oldest written material on papyrus dates back to B. The Romans created a reed-pen perfect for parchment and ink, from the hollow tubular-stems of marsh grasses, especially from the jointed bamboo plant. They converted bamboo stems into a primitive form of fountain pen. They cut one end into the form of a pen nib or point. A writing fluid or ink filled the stem, squeezing the reed-forced fluid to the nib. The writing instrument that dominated for the longest period in history over one-thousand years was the quill pen.
Introduced around A. Goose feathers were most common; swan feathers were of a premium grade being scarcer and more expensive. For making fine lines, crow feathers were the best, and then came the feathers of the eagle, owl, hawk, and turkey.
Plant-fiber paper became the primary medium for writing after another dramatic invention took place: Johannes Gutenberg invented the printing press with replaceable wooden or metal letters in Simpler kinds of printing e. The letter forms we use today were not always, as we see them now. Over the past years, they evolved, linked to the rise and fall of civilizations, different cultures adding their own distinct imprint on the symbols of language. Johannes Gutenberg, who cast individual blocks out of lead, each bearing a raised letter, invented printed letters in the fifteenth century.
In Gutenberg's system, thousands of metal characters are stored in graded wooden cases and assembled by hand into fields of text. The printer inks the raised surfaces of the letters and passes the type and paper through a press.
After the job is printed, the metal letters returned to their cases, ready to be composed into new texts.
